I have to ask that is it mentioned in the Quran or Hadith that benefits of reciting Quran can be sent to the deceased. If yes, please provide me with the hadith No. I need to know it because whenever I read Quran I make dua for my Marhoom (late) father but few days back someone told me that reciting Quran is not for the deceased.

There are other narrations in this regard. Allama Ibn Taimiya in his Fatwas and his disciple Allama Ibn al-Qayyim in his book Kitab al-Rooh has explained this matter in detail. Briefly, it means that it is established the rewards of the good deeds can be dedicated to the dead.
